The use of the Mobil Rarus 800 Series oils can result in cleaner compressors and lower deposits compared to conventional mineral oils, resulting in longer running periods between maintenance intervals. Their excellent oxidation and thermal stability safely allow extended life capability while controlling sludge and deposit formation. They possess outstanding anti-wear and corrosion protection, which enhances equipment life and performance.
Features | Advantages and Potential Benefits |
High-Performance Synthetic Base Stocks | Significant performance capabilities relative to mineral oils Improved safety |
Low Ash and Carbon Formation | Improved valve performance Reduced deposits in discharge lines Reduced potential for fires and explosions in discharge systems Improved compressor performance |
Outstanding Oxidation and Thermal Stability | Longer oil life Improved filter life Lower maintenance costs |
High Load-carrying ability | Reduced wear of rings, cylinders, bearings and gears |
Excellent Water Separability | Less carryover to downstream equipment Reduced sludge formation in crankcases and discharge lines Reduced blockage of coalescers Less potential for emulsion formation |
Effective Rust and Corrosion Protection | Improved protection of valves and reduced wear of rings and cylinders |
The Mobil Rarus 800 Series oils are recommended for single and multistage air compressors but are not recommended for air compressors used in breathing air applications. They are particularly effective for continuous high-temperature operation with discharge temperatures up to 200ºC. They are suitable for reciprocating and rotary type machines with the lower viscosity grades mainly used in rotary compressors. Rarus 800 Series oils are recommended for units with a history of excess oil degradation, poor valve performance or deposit formation. They are compatible with all metals used in compressor construction and with mineral oil-based lubricants but admixture will detract from their performance capabilities. Mobil Rarus 800 Series oils are compatible with seals made from fluorinated hydrocarbon, silicone fluorosilicone polysulfide, Viton, Teflon, and high nitrile Buna N NBR (above 36% acrylonitrile) materials. Materials not recommended include low nitrile Bune N NBR (below 30% acrylonitrile), natural and butyl rubbers, Neoprene, polyacrylate, styrene/butadiene and chlorosulfonated polyethylene.
Oil resistant paints are not affected by Mobil Rarus 800 Series, but lacquer, varnish, PVC and acrylic paints are not recommended.
The following types of compressor applications have shown excellent performance with the Mobil Rarus 800 Series oils:
